Because the material of the bolt is chromium molybdenum (SCM) 435 and cold forging (screw rolled) products, it can be used with confidence in strength. The price is also relatively inexpensive and rich in variety. Quantity can also be selected from a small amount to a box unit, so it is useful. Especially strength is firmly stamped numerically on the bolt face, so you can reliably and reliably. It is very handy. It is just the cheapest, the strongest bolt.
